The thing is absolute Schrott.Funktioniert not even on a normal PC with Windows 7. Automatic software recognition u.installation (windows 7 standard in 95% of all programs) is not possible because the driver for iris Pen7 not be downloaded from the Internet is directly available , You have to order drivers download each separately register lassen.Nach 3 hours I then with 17 trick by not clicked the Setup icon, but all program files installed individually, the thing to scan gebracht.Aber it only worked for 10 minutes with a high error rate ..Kleine letters u.Zahlen (eg bank transfer documents from paper) were not correctly identified. The writing had to be big u. The paper was not allowed to even gray or yellowed sein.Man was not allowed to slow over the row of letters go technically ausgereift.wäre a nice toy for a maximum of 10 euros, but at 50 euro a waste geld.Ich have it returned u. Amazon has refunded me some money without hesitation.
